Yog vim li cas tawg

Cracking yog tseem ceeb rau ob qho laj thawj tseem ceeb: Nws pab kom phim cov khoom ntawm cov feem ntau nrog qhov kev thov rau lawv. Nws tsim alkenes, uas yog pab tau raws li feedstock rau petrochemical kev lag luam

Hauv qhov no, lub hom phiaj ntawm kev tawg yog dab tsi?

Kev tawg , nyob rau hauv roj av refining, cov txheej txheem los ntawm hnyav hydrocarbon molecules yog tawg mus rau hauv lub sib zog molecules los ntawm lub tshav kub thiab feem ntau yog siab thiab tej zaum catalysts. Kev tawg yog cov txheej txheem tseem ceeb tshaj plaws rau kev lag luam tsim cov roj av thiab cov roj diesel.

Tom qab ntawd, lo lus nug yog, ob hom kev tawg yog dab tsi? Hom Cracking - Cua sov Kev tawg thiab Catalytic Kev tawg . Kev tawg yog ib tug txheej txheem uas complex high molecular hnyav cov organic tebchaw yog tawg mus rau hauv me me fragments ntawm molecules. Lub complex siab molecular hnyav organic tebchaw yog feem ntau ntev chained hydrocarbons xws li roj av.

Tsis tas li ntawd, vim li cas peb rhuav tshem cov saw ntev hydrocarbons?

Cracking pub loj hydrocarbon molecules ua tawg mus rau hauv me me, ntau pab tau hydrocarbon molecules. Cracking ua ib qho kev sib xyaw me me alkanes thiab alkenes. Qhov no pab ua kom tau raws li qhov xav tau ntawm cov khoom siv feem ntau thiab kom tau txais txiaj ntsig.

Yuav ua li cas alkanes tawg?

Kev tawg yog ib qho tshuaj tiv thaiv uas loj saturated hydrocarbon molecules tau tawg mus rau hauv me me, muaj txiaj ntsig zoo hydrocarbon molecules, qee qhov tsis txaus ntseeg: thawj qhov pib hydrocarbons yog alkanes . cov khoom ntawm tawg suav nrog alkanes thiab alkenes, cov tswv cuab ntawm ntau homologous series.
